Rydberg states of alkali atoms, where the outer valence electron is excited to high principal quantum numbers, have large electric dipole moments allowing them to be used as sensitive, wideband, electric field sensors. These sensors use electromagnet

We demonstrate a large instantaneous bandwidth optical cyclostationary processor that computes the spectral correlation function. Post-processing of experimentally measured SCFs is applied for waveform characterization, specifically baud rate and pul

We experimentally demonstrate an optical architecture that computes the spectral correlation function of high bandwidth waveforms, employing the conjugate multiplication of signals via four-wave mixing in optical fiber. The SCF provides information r

We propose and experimentally demonstrate a cyclostationarity-based, blind architecture for the classification of arbitrary, coherent waveforms, with minimal receiver-side demodulation DSP. The method enables baud rate estimation, CD estimation and,

We present a method for linear impairment emulation of optical signals using transmit-side DSP to enable the generation of realistic stressed waveforms and thus the testing of receivers without the network. We experimentally demonstrate CD and phase

We propose a blind technique to identify the number of polarization in an optical signal using Principal Component Analysis (PCA). Experimental results verifying the proposed technique are presented. Additionally, the relation between PCA and Indepen

We present an efficient model for simulating distortions imposed by DACs in high-speed optical links. Theoretical stand-alone and experimental system-level validations ensured consistency of simulations with theory and experiments from our testbed.

The rapidly changing RF landscape creates a requirement for flexible frequency access as well as the ability to move signals over long distances. This paper presents the characterization and experiments of a wide band photonics enabled transceiver. T

Classical square 64 QAM constellation may be easily generated. However, the noise processes and impairments in a coherent optical link may render this constellation non-optimum. We identify the ENoB requirements necessary to fully realize the benefit
